A distortion pedal that delivers the gritty sounds of early punk, new-wave, and rock bands from the 70s and 80s.

The Hartman Electronics LM308 Op-Amp Distortion guitar pedal offers two modes of distortion inspired by the edgy, modern, dirt tones popularized by punk, new-wave, and college-rock bands of the late 70s and early 80s. Distortion modes are selectable on-the-fly via a second stomp switch. Mode (A) employs a diode-clipping stage to produce a classic distortion and crunch of the original circuit, exhibiting the same sensitivity to player pick-attack, palm-muting- and pinch-harmonics. The second distortion mode (SYM) transforms the pedal into an overdrive, increasing transparency, headroom, and dynamic response, with output levels suitable for overdriving the input of amplifiers or other devices downstream. Your strat sounds like a strat, your LP sounds like an LP. No more masking the tone of your instrument, but still plenty of scream, crunch, and sustain.

  • Original metal-can type LM308AH Op-Amp
  • Second footswitch for changing distortion modes
  • Dual LED indicators
  • Heavy-duty True-bypass switching
  • 9V battery included

Comments about Hartman Electronics LM308 Op-Amp Distortion Guitar Effects Pedal:

I've put off getting a RAT clone for a while. I'm not sure why, I reckon there was some sort of 80s hair metal stigma attached to this in my mind. I picked up this Hartman because MF was blowing them out for 100 bones.

Mind blown.. I've been looking for that 90s rock sound and I had never been able to really nail that with a DS-1, even modded, but here it is. Back off of it and it does a nice crunch for classic rock and it cleans up with the volume knob on the guitar. It is very responsive to pick attack. What a lovely pedal, no bad sounds no matter where the gain is and it loves my Marshall amp and both of my guitars.

Would I buy it again if stolen, abosultely. If I could have one dirt pedal this would be it.
